Just thought I would give a short up date, I re-adjusted the mixture and got it to run albeit shockingly rich, moved it out of the garage to tidy up and reversed back in after sweeping the garage floor to find about a litre of power steering fluid on the floor and a long trail of the fluid had followed me in. Now looks like a new service kit needed for the rack
I haven't fitted a new thermostat yet either. I will get there though......one day
